1. A copying machine, comprising: a photosensitive member in the form of an elongated web supported for movement past an exposure station by a supply reel and a take-up reel; housing structure including means for supporting the supply and take-up reels and a plurality of guide rolls; removable support structure insertable into said housing structure and removable therefrom; and a plurality of guide rolls carried by said removable support structure, said guide rolls carried by said support structure cooperating with said guide rolls supported by said housing structure to guide and support the photosensitive member for movement within said housing structure.
 2. Structure as specified in claim 1 wherein, each of the guide rolls of said housing structure cooperating with guide rolls carried by said support structure cooperates with a single guide roll of said support structure to thereby form pairs of guide rolls.
 3. Structure as specified in claim 2, further including resilient means associated with at least one roll of each pair of guide rolls for biasing of said at least one guide roll into engagement with the other roll of that pair of guide rolls.
 4. Structure as specified in claim 2 including, a guide roll carried adjacent the leading edge of said removable support structure for supporting said photosensitive web adjacent a developer applicator.
 5. Structure as specified in claim 1 wherein, said guide rolls supported by said removable support structure are in spaced apart relationship to allow passage of said take-up reel therebetween.
 6. Method of installing a photosensitive material into reproducing apparatus, said method including the steps of: installing a reel containing a new supply of photosensitive material into said apparatus; passing the free end of said material between a pair of spaced apart guide rolls carried by a photosensitive support structure; securing the remote end of said photosensitive material in said apparatus; and inserting said photosensitive material support structure into a housing forming part of the apparatus.
 7. The method of claim 6 wherein, the step of installing comprises placing a take-up reel attached to the free end of said material in cooperative engagement with drive yokes carried by said apparatus.
 8. In reproducing apparatus in combination, housing structure having opposed walls with guide rail members carried thereby; a supply reel and a take-up reel for reproducing material; means for supporting said reproducing material intermediate said supply reel and said take-up reel; said supporting means comprising a plurality of quide rails extending along said opposed walls intermediate thereof; a removable drawer structure supported by said guide rails; and a plurality of guide rolls supported by said drawer structure cooperating with guide rolls supported intermediate said opposed walls for guiding and supporting said material for movement between said supply reel and said take-up reel.
 9. Structure as specified in claim 8 wherein, each of the guide rolls supported by said opposed walls cooperates with one of the guide rolls carried by said drawer structure to sandwich said reproducing material therebetween.
 10. Structure as specified in claim 9 further including a means associated with at least one guide roll of each pair for biasing said roll into engagement with the other roll of the guide roll pair.
 11. Structure as specified in claim 8 including, a backup roll carried adjacent the leading edge of said removable drawer structure for supporting a portion of said reproducing material adjacent a developer applicator.
 12. Structure as specified in claim 8 wherein, said guide rOlls supported by said removable drawer structure are in a spaced apart relationship for allowing passage of said take-up reel therebetween.
 13. Structure as specified in claim 11 including a backup roll carried adjacent the leading edge of said removable drawer structure for supporting a portion of said reproducing material adjacent a developer applicator.
 14. Structure as specified in claim 13 wherein, said guide rolls supported by said removable drawer structure are spaced apart for allowing passage of said take-up reel therebetween.
